Application filed April 18, 1921.

T 0 all whom it mayconcern:

Be it known that I, OSCAR C. SCHROEDER, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Apparatus for Feeding and Measuring Oils, Etc, of which the following is a full, clear, and exact specification.

My invention is concerned with apparatus designed primarily for feeding fuel oil from an underground tank 'to a burner, and is designed to produce a simple and effective apparatus whereby oil or some similar liquid may be displaced automatically from a tank in measured quantities by water or some other liquid under pressure that is heavier and will not mix with the displaced liquid when introduced into the tank.

It is further concerned with such apparatus provided with a counter operated thereby so that the exact amount of oil passed through the apparatus may be known at any time.

To illustrate my invention I annex hereto a sheet of drawings in which the same reference characters are used to designate identical parts in all the figures, of which- Fig. 1 is a side elevation of an apparatus embodying-my invention; and v Fig. 2 is a sectional view on an enlarged scale showing a portion thereof.

In illustrating my invention, I have shown, somewhat diagrammatically, a furnace 10 provided with an oil burner 11, which may be of the centrifugal atomizing variety shown in my application No. 462,376 filed Apr. 18, 1921, for Letters Patent of the United States, which consumes the oil raised from a small receptacle 12 which is kept filled to a constant level from the pipe 13 by a float controlled apparatus 141, seen in dotted lines.

The oil is kept in a tank 15, which is preferably buried in the ground outside of the building represented by the brick wall 16, and which is provided with an inlet in its top controlled by the three-way valve 17 having the pipe 18 running to the opening 19 for filling the tank, and also the pipe 20 running to the measuring receptacle; 21. At the bottom, the tank is provided with an inlet 22 connected by the pipe 23 with a three-way valve 24, which is also connected to the discharge pipe 25 leading to the Patented Mar. 28, 1922. Serial No. 462,375.

sewer, and with the supply pipe 26 leading to the city mains, or any other suitable supply of water under pressure. The receptacle 21 preferably takes a cylindrical form, open atthe top, and closed at the bottom encept for the openings therethrough to the pipes 13 and 20. The pipe 26 has located therein above the top of the receptacle 23 a valve casing 27, which contains the shutoff valve with its stem 28 projecting out through the valve casing. Loosely pivoted to the stem 28 is an operating lever 29 which has pivoted to its outer end the rod 30,which depends in thereceptacle 21 to near the bottom thereof. Surrounding the rod 30 is a preferably hollow float 31, and the rod is provided with a pair of abutments 32 and 33 adapted to be engaged alternately by the top and bottom of the float. The abutment 32 is fixed, but the abutment 33 is adjustable, preferably taking the form of a nut threaded on the upper end of the rod 30. lVhen the valve 27 is opened, with the valve 24 adjusted to connect the pipe 26 with the tank 15, and with the valve 17adjusted to connect the tank with the pipe 20, the water flows down through the pipe 26 into the bottom of the tank, forcin some of the oil therefrom up through the pipe 20, filling the receptacle 21 until the rising float 31 engaging the abutment 33 lifts the outer end of the lever 29, as seen in dotted lines, far enough to turn the valve to shut off the water supply as hereinafter described, when of course the flow of the oil ceases. The valve 27 remains in the closed position until the oil falls in the reservoir to its lower level and it engages the abutment 32, and eventually swings the lever 29 to again open the valve 27. By carefully sition of the nut 33, it will be obvious that the apparatus can be made to measure an exact amount of oil at each filling and emptying of the receptacle, and I preferably make the adjustment such that a gallon of oil is delivered at each reciprocation of the rod 30. To register the number of allons passing through the apparatus, I preferably secure on the pipe 26 above the valve casing 27 any ordinary form of a counter 34 which has the swinging operating arm 35 connected to its counter-operating rock shaft in the customary manner. To operate the register and turn the valve stem 28, I secure on the valve stem an arm 36 which is adjusting the poconnected by a link 37 with the arm 35, the joints between the arms and links being of the universal variety so that they can operate in spite of the fact that the outer end of the arm 36 swings through the arc of a circle. In the full line position shown in Fig. 2, the arm 35 and the link 37 form a preferably obtuse angle extending outwardly from the valve and counter so that when the arm 36 is swung upward, the angle will be rendered more acute to allow the necessary rocking of the arm 35. In order to move the valve quickly at the completion of the movement of the lever 29 by the float in either direction, I connect a strong helically coiled spring 38 to the outer end of arm 36 and to the middle of the lever 29, so that when the lever 29 is raised by the float to the dotted line position the spring 38 passing the center and operating against the arm 36 will lift the latter to shift quickly thevalve and operate the register, and vice versa.

While I have shown and described my invention as embodied in the form which I at present. consider best adapted to carry out its purposes, it will be understood that it is capable of modifications and that I do not desire to be limited in the'interpretation of the following claims except as may be necessitated by the state of the prior art.

\Vhat I claim as new and desire to secure by Letters Patent of the United States is:
